A man and woman wore latex gloves while robbing a cab driver in the unincorporated community of Broadmoor last month, prosecutors said, but the handwear reportedly had the opposite effect of covering their tracks.

Thomas Mason McCall III, 22, of San Francisco, and Lakeisha Marie Franklin, 31, of San Leandro, are expected in court today for a preliminary hearing in connection with the brutal robbery near Broadmoor Middle School on April 21. They remain in custody on $50,000 bail and are scheduled to appear in court today for a preliminary hearing.

Prosecutors said the germs claimed they had no money when the cab driver reached their destination. They reportedly asked to borrow a phone so they could call to have someone bring the fare.

While Franklin pretended to make that call, McCall allegedly punched the cabbie and demanded his cash, San Mateo County District Attorney Steve Wagstaffe said. They got away with both the cash and phone, Wagstaffe said, but not for long.

Investigators soon got a call from another cabbie who said he was dispatched to a motel to pick up a man and woman, but refused to drive them because they were wearing latex gloves.

The cabbie directed police to the motel, where they not only found Franklin and McCall but also “several children,” Wagstaffe said.

The suspects were positively identified by the cab driver who was robbed, Wagstaffe added. Additionally, video surveillance from inside the cab shows the pair attacking the cab driver.
